Default Smokes when starting.....

Not everytime...but sometimes...whenever I start the car, after it sits a while, I notice a blue/white smoke come out the tailpipe...then it's gone. Not much of it just a quick "burst". What does that mean? I check the oil....about 1200-1500 miles to a quart (acceptable)...engine runs strong....gets about 15 mpg. Any info on this will be appreciated!

Sounds like the valve stem seals are worn.

I would check intake manifold bolts (especially if you run an aluminum intake with cast heads).
Check your PCV valve as well...that was my problem.

Thanks! I really appreciate that! I got the wiper cover from Ecklers and then painted it to match the car.

Could just be a rich condition if it is closer to black smoke. But blue smoke is most likely valve guides/seals.

Your drainbacks could also be clogged, causing oil to pool in the heads, as well as worn valve seals/guides.
